Dunno, it look to me the props were turning when it nosed over. Was it because the props were windmilling inspite of the relative slow airspeed?
Anyway I look at it, the pilot did what he was suppose to do and that was fly it til it quit flying. Did a great job holding the nose up, though going on memory, not sure if the tail touch the runway as he pulled back several times pretty hard on the yoke keeping the nose up. Don’t remember sparks or anything like that.
There was another king air gear up landing where the pilot feathered the props as he crossed the numbers and you could clearly see the props were stopped as he flew the plane down through ground effect. If I remember as he crossed the runway threshold, he feathered the props.
Of course, me being a single engine piston jockey, easier to Monday nite quarterback then flying the emergency, so take it for what it’s worth.
Don’t have the link handy here, but can get the link at home or if anybody wants the video, I do have the video on my hard drive.
